Calibration at the customers site must be done under the following conditions:
Changing the pcb, extrenal EEPROM, B4 humidity sensor, Pressure sensor P1, replacing the
air baffl e or divider plate between the 2 fan motors of a fl oor model, fan motor, detaching of the fan wheel and
installation of the appliance above 1000m (3000ft) above sea level or below sea level (dead sea).
Basic condition Cabinet sensor B1 Quench. sensor Humidity sensor
Temperatures: B1 <40°C B2 <45°C B4 < 40°C
Basic condition Heating: OFF Fan motor: OFF Humidity fl ap: Closed
Hardware: Side panel must be fi tted; Unit must be clean, but may be wet
In order to achieve the best possible calibration values, insert
2 GN-container 20 or 40 mm deep with the opening facing downwards
in 61 and 62 units into rail 2 and 5
in 101 and 102 units into rail 3 and 7
in 201 and 202 units 3 GN container into rail 3, 10 and 17
